Sheffield Wednesday owner Dejphon Chansiri says hiring Tony Pulis was a "mistake" he will not make again when recruiting his successor.
Neil Thompson will continue in temporary charge, having guided Wednesday to a 2-1 win over Middlesbrough less than 24 hours after Pulis' dismissal.
The former Stoke, West Brom and Crystal Palace boss was only appointed in November but registered just one win in 10 matches.
Chansiri held an online press conference on Thursday morning at which he discussed the search for a new manager.
"I need to bring in the right one," he said. "I thought Pulis was the right one but I was totally wrong. I can't make a mistake this time.
"After I sacked Pulis, many offers came in but I can only choose one. I need to make sure it is the right one. We are still working. I will try to make a decision as soon as possible.
"My people need to help me make a shortlist and then we'll look at it. Then we'll start to interview.
"This time we need to think more and more. I don't want any surprises again."
Pulis is understood to have been surprised, disappointed and hurt by the comments made by Chansiri.
Sky Sports News were told that Pulis wanted to leave the club with dignity and respect. However, he feels that became impossible to achieve.
Pulis offered to leave Wednesday on mutually agreed terms, which would have seen him leave without a payoff, but the club would not accept that and chose instead to sack him.
During his short period at Hillsborough, Pulis felt he had a good working relationship with both the players and staff.
